Deucravacitinib: First Approval

Deucravacitinib (SOTYKTU™) is a first-in-class, highly selective, oral tyrosine kinase 2 (TYK2) inhibitor. It acts via an allosteric mechanism, binding to the catalytically inactive pseudokinase regulatory domain of TYK2 and stabilizing an inhibitory interaction between the regulatory and catalytic domains. Deucravacitinib is being developed by Bristol Myers Squibb for the treatment of multiple immune-mediated diseases, including psoriasis, psoriatic arthritis, lupus and inflammatory bowel disease. It received its first approval (in the USA on 9 September 2022) for the treatment of adults with moderate-to-severe plaque psoriasis who are candidates for systemic therapy or phototherapy. On 26 September 2022, it was subsequently approved in Japan for the treatment of plaque psoriasis, generalized pustular psoriasis and erythrodermic psoriasis. The Marketing Authorisation Application for deucravacitinib for the treatment of adults with moderate to severe plaque psoriasis has been validated in the EU, and clinical development of the drug for the treatment of multiple immune-mediated diseases is underway in numerous countries worldwide. This article summarizes the milestones in the development of deucravacitinib leading to this first approval for the treatment of adults with moderate-to-severe plaque psoriasis who are candidates for systemic therapy or phototherapy.
